A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 1, 2, 12, 13 are rejected under 35 U.S.C. 103 as being unpatentable by Udagawa (US20190265695) in view of Kovacek (US20200317223) and King (US20210354725).
Regarding claim 1, Udagawa teaches a method for determining an overall route for a vehicle to operate in an autonomous driving mode, the method comprising:
determining, by the one or more processors of a computing system, a plurality of possible paths by the vehicle along the overall route ([0046] disclosing an overall route of the autonomous vehicle to the destination. [0070]-[0080] disclosing determining different routes that satisfy a safety margin. [0059] disclosing the control device controller includes a processor and controls the vehicle. [0084] discloses the route to an overall trajectory and the determining of local target paths along the target overall trajectory. [0087]-[0089] disclosing determining if a target path satisfies a safety margin, if the safety margin is not satisfied, a new target path is created. This is interpreted as determining a plurality of possible paths for a given driving maneuver in order to follow a planned target trajectory along a route);
determining, by the one or more processors based on the received sensor data and the plurality of possible paths, a kinematic feasibility of each possible path according to a kinematic model of the vehicle ([0087]-[0090] disclosing determining whether a path safety margin is satisfied with respect to the size of the vehicle “kinematic model”, i.e. kinematic feasibility of each possible path according to a kinematic model of the vehicle);
selecting, by the one or more processors, a given one of the possible paths based on the kinematic feasibility ([0092] disclosing the target vehicle adopting the target path. [0087]-[0090] disclosing the target path is chosen based on kinematic model of the vehicle and based on making a lane change from a merge lane “lane indicators”, i.e. based on kinematic feasibility); and
generating, by the one or more processors, a trajectory for the vehicle based on the given path ([0087]-[0092] disclosing following the target path based on the kinematic feasibility. It is interpreted that plurality of local target paths are generated, i.e., a trajectory is generated. It is also interpreted that the path that the vehicle follows is the trajectory that the vehicle follows. See also [0084] disclosing the target path includes trajectory of the vehicle);
providing, by the one or more processors, the trajectory to the vehicle for making real-time driving decisions in the autonomous driving mode ([0087]-[0092] disclosing following the target path based on the kinematic feasibility).
Udagawa does not teach and a hierarchy of stored rules, the hierarchy of stored rules being associated with one or more of lane indicators, physical road components or temporal restrictions of the vehicle.
Kovacek teaches and a hierarchy of stored rules, the hierarchy of stored rules being associated with one or more of lane indicators, physical road components or temporal restrictions of the vehicle ([0034]-[0036] disclosing selecting a navigable route for the vehicle from among navigable routes based on a hierarchy of priority factors “rules”, wherein the priority factors being associated with vehicle restriction. [0048] further disclosing the day restriction is taken in consideration, i.e., temporal restriction, the same paragraph also applies to road restrictions).
Udagawa and Kovacek are analogous art because they are in the same field of endeavor, vehicle routing. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the teaching of Udagawa to incorporate the teaching of Kovacek of the hierarchy of stored rules being associated with one or more of lane indicators, physical road components or restrictions of the vehicle in order to select an optimal route based on the hierarchy of priority factors as taught by Kovacek and achieving an optimal operation of a vehicle in a most efficient mode [0034]-[0036].

It is obvious to combine the teaching of King with the teaching of Udagawa as modified by Kovacek yielding predictable results and improving driving safety when the vehicle turns since the vehicle sweeps more volume when turning at a tight corner as taught by King [0203]-[0208].
Regarding claim 2, Udagawa as modified by Kovacel further teaches the method of claim 1, wherein determining the kinematic feasibility of each possible path includes evaluating a legal restriction.
Specifically, Kovacek teaches wherein determining the kinematic feasibility of each possible path includes evaluating a legal restriction ([0048] disclosing a driving restriction when the air quality is low, i.e., this is a legal restriction through the local municipality and since it is timed for a day thus it is also a temporal restriction).
It is obvious to one of ordinary skill in the art to combine the teaching of Kovacek of a legal restriction with the teaching of Udagawa yielding predictable results in order to obey all rules and select most optimal route that obeys all legal restrictions and thus avoiding delays and tickets.

An example is given in [0024] a highway may not be the fastest route at a certain time. It can be interpreted that the temporal restriction to the highway occurs at that certain time and the vehicle does not need to reroute in any other time, i.e. the likelihood that the vehicle will be able to perform the driving action before the occurrence of the temporal restriction).

Response to Arguments
Applicant’s arguments filed on 02/19/2026 have been fully considered but they are not persuasive.
With respect to applicant’s arguments that “since selecting is based on kinematic feasibility, claim 1 first determines kinematic feasibility for each path before selecting a given path. A claim requires an ordering of steps when the claim language, as a matter of logic or grammar requires that the steps be performed in the order written, or the specification directly or implicitly requires an order of steps…. In contrast Udagawa tonly generates a single target path, which it then checks against a safety margin…thus Udagawa generates a target path and merely adjusts the target path iteratively if necessary. In contrast the claimed approach evaluates a plurality of possible paths before selecting a path”, Udagawa in at least [0070]-[0085] discloses the steps of determining a route before determining a kinematic feasibility and if the route does not meet the kinematic feasibility, it creates an alternative route and determines feasibility of the alternative route and the process repeats until the route is selected based on the kinematic feasibility and plurality of paths. The claim language requires determining the kinematic feasibility of each path after determining the path, but does not explicitly require determining all the paths and then determining kinematic feasibility of each path at the same time. Thus Udagawa selects the path after evaluating a plurality of the first path and at least one alternative paths against kinematic feasibility when the first path fails to meet kinematic feasibility. Thus the “Before” limitation is met since the kinematic feasibility of each path is determined before selecting the final path.
Claim 1: determining a plurality of possible paths…along the overall route (Udagawa teaches the limitation in [0070]-[0085] disclosing determining a route and then determining other alternative routes by rerouting.
Determining, by the processor based on the plurality of possible paths, a kinematic feasibility of each path according to a kinematic model of the vehicle (Udagawa teaches the first path is determined then kinematic feasibility of the first path is determined, then an alternative path is determined and kinematic feasibility is determined for second path)… thus the order of determining kinematic feasibility of each path after determining the path is met by Udagawa and the claim limitation is met.
Selecting… a given one of possible paths based on the kinematic feasibility (Udagawa in [0070]-[0085] discloses selecting the path based on the kinematic feasibility of the plurality of paths, since the first path kinematic feasibility fails to meet the threshold, thus the second path is selected based on the kinematic feasibility)…thus Udagawa teaches the selection of a given possible path based on the kinematic feasibility.
Thus based on the claim language, the claim requires the order of determining kinematic feasibility of each path after the path is determined and selecting the path based on the kinematic possibility which is taught by Udagawa. the selection by Udagawa is done based on the kinematic feasibility of each path, after a first path is determined to fail the kinematic feasibility, another path is checked for kinematic feasibility and is selected when it meets kinematic feasibility.
